Is it possible to have a physical picture how Yin and Yang are coupled? Several systems like Taoism speak in an abstract way about the dual composition of objects and living creatures but it was never explained or shown in a logic way how that can happen in reality. The concept of topological holons can help us to visualize that yin-yang coupling in a logic way, ruled by cause and effect.

The first step is to understand that the cosmological singularity can be a hollow spherical non-breakable dynamic membrane, which is to be consider a real energy carrier, similar but not just on the abstract level of Spinoza's and Leibniz "absolute substance". To me the membrane is a real unity (the whole). The surface of this membrane oscillates in zillions and zillions of continuous up and down going peaks, of different size.

At this level the membrane is pure energy (cfr. Frank Wilczek), and is in a state of non-dual not-being (Wu Chi). The membrane has however the possibility or potency to restructure itself in sub-sets. This can happen when an active part of the membrane penetrates a passive part of the membrane, that way creating a local multi-layered space, which is a UNION (a co-existing yin part and yang part).

In next image you can see the synthesis of this concept.

Since everything (all objects, all living creatures) are topological spaces (holons), they all have unique active (yang) and passive (yin) energies in their own system/structure. They all are unique because the degree, quantity, etc. of yin and yang in their system differs from the yin-yang compositions in these of others. So they appear different, and act differently. Where they also have Chi energy, which is transported and distributed by the proper (internal Chi channels) and external membranes.

The mathematic correctness is obvious. We start from a unity, where the unity (the membrane) generates subsets. So one (1) always stays one (1), even if the second part of the equation is divided in smaller values. This is shown in next image.

In reality there will no absolute values since all holons and their layering structure and internal sub-holons are constantly changing due to the dynamics of the membrane, the dynamics of the holons and the energy exchange between holons. In addition to this the membrane is flexible, so it has an elastic property ( tension, local stretching, pulling back, stress).

The principles of yin-yang coupling are shown in a dynamic way in next image. The image starts with a spherical membrane with two progressing peaks, both being yang. These two yang peaks are two local manifestations of the Wu Chi energy. Where Wu Chi is fundamental, these two peaks are temporary, impermanent.

During the progress one peak comes in a passive position. This peak becomes "receptive" for the force of the other peak. Therefore this peak - just by it's topological position - becomes Yin.

Where the Yang peak still has one (1) surface, the yin peak (tube) has - by it's orthogonal position - two (2) surfaces.
The yang peak penetrates (pushes-away) in two steps a part of each of these two sides. Each step a new yin cover goes over the yang peak. That results in a topological space (a holon) which has 3 layers.

The most simple holons have three layers. A yang layer covered by two yin layers. The first inside yin layer can be called the yin inner layer, and the other: the outer yin layer.

This new concept tells maybe the real origin of the yin and yang symbols; where the symbol of yin has two shorter lines, and the symbol of yang has a single larger line .

The penetration of the yin energy peak by the yang peak is in fact a topological division of the yin energy peak. The force of the yin energy - originally itself a yang energy peak - is split in two separate layer positions (so spread over much larger surfaces), and the motion or movements of these two yin layers is stipulated by the force, motion and vibrations of the central yang peak.

As such - in a holon - the inner yin layer is the mediator, interface or intermediary between yang and the outer yin. They can not have direct contact.
However between the inner yin layer and the outer yin layer a number of new direct couplings can happen, just like a different type of couplings can happen between the inner yin and the yang layer.

Where in biology the inner yin layer will be the mesoderm, the outer yin layer will be the ectoderm, and the yang layer the endoderm layer. Stem cells have the capacity to be pluripotent.
And indeed the endoderm is related to yang processes, such as the receipt of energy from the outer world by the gastrointestinal tract and the respiratory tract, and their inside distribution by the endocrine glands and organs (liver and pancreas).

The embryonic nervous system is a hollow tube consisting of elongated neural progenitor cells, which extend from the inner to the outer surface of the tube. In a section inside the tube called the ventricular zone (VZ), these cells divide and produce immature neurons that migrate outwards. This involves well-characterized movements that are coupled to cell division. After a cell divides at the inner-most VZ region, the nuclei migrate to the outer region, where they synthesize new DNA before returning. More information: Kosodo, Y., et al. Regulation of interkinetic nuclear migration by cell cycle-coupled active and passive mechanisms in the developing brain. The EMBO Journal 30, 16901704 (2011).
This new holonic approach of yin and yang can be used to analyze and understand a number of phenomenon in our universe such as the structure of atoms, the magnetic field(s) around a moving electron, or i.e. the so-called "hard problem" of body and mind.

By this holon approach we can examine the concept of WU Xing or the five basic elements (fire, earth, metal, water and wood) or movements.
These five elements are each specific combinations of holons (membrane spaces). On the webpage holon growth are shown the various combination. The first basic holon-type is called 2*. Which can combine in two ways: as the holon-type 3A and type 3B (see webpage). Each of them can combine in a yang and a yin way. In total five combinations are possible, these are the five elements.

Next we look more into the energetic geometry which is the base for the five wu xing phases (elements).

We call first holons the 2* type. These 2* holons are the basic spaces.

This is the first step/process how in the Einstein formula E is converted in M or C.

Parts of Pure Energy are coupled to make a first structure that has 3 layers.
We can say that pure energy slows down in such a 2* holon.

When a 2* holon couples with itself it makes a 9-layered space (holon type 4E), which we can FIRE.

The first holons of the 2* typecan combine with a yin OR a yang membrane peak to make a larger holon. This way the holons 3A-type and 3B-type are made.

A 3A-type is made when an expanding 2* holon penetrates a Yin (passive, receptive) membrane peak. 3A becomes the base for the Water and Earth phase (element)

A first holon of the 2* typecan combine with a yang membrane peak to make a larger holon. This way a holon 3B-type is made.

A 3B-type is made when an expanding 2* holon is penetrated bya Yang (active, pushing) membrane peak. 3B becomes the base for the Metal and Wood phase (element)

In the above image we see the energetic design of the first holon-type 2* leading by a self-pelastration to the holon-type 4E. The 4E-type holon has 9 layers and is the FIRE of Wu Xing. The same result can be reached when a 2*-holon pelastrates another 2*.

In the above image we see the two different ways the 3A holon type can combine. First we see how the 3A holon penetrates a yin membrane peak (here 3A is active) and then we see how the 3A holon is penetrated itself by a Yang membrane peak (here 3A is passive). The new holons (4A and 4B) have different layers, namely Water (4A) has 7 layers, and Earth (4B) has 11 layers. This means that we see that in the Einstein formula E=MC^2 local E (Energy) can convert in different type of structural deformations (4A and 4B) of the (spacetime) membrane. This can mean two different type of fundamental or elementary particles. Conceptual a 4A type will be more bosonic (energetic, C) where a 4B type will be more fermionic (Matter-related, M).

In the above image we see the two different ways the 3B holon type can combine. First we see how the 3B holon penetrates a yin membrane peak (here 3B is active) and then we see how the 3B holon is penetrated itself by a Yang membrane peak (here 3B is passive). The new holons (4C and 4D) have different layers, namely Wood (4C) has 9 layers, and Metal (4D) has 15 layers. This means that we see that in the Einstein formula E=MC^2 local E (Energy) can convert in different type of structural deformations (4C and 4D) of the (spacetime) membrane. This can mean two different type of fundamental or elementary particles. Conceptual a 4C type will be more bosonic (energetic, C) where a 4D type will be more fermionic (Matter-related, M).The concept of the coupling by a cosmic penetration of Yin and Yang peaks that is explained above may find a confirmation in the Bhagavad Gita. Chapter 7, verse 11: "I am the strength of the strong, devoid of passion and desire. I am sex life which is not contrary to religious principles, O lord of the Bharatas [Arjuna]."

A number of other verses of the Bhagavad Gita also seem to confirm our holon approach, such as:Verse 9.4: "By Me, in My unmanifested form, this entire universe is pervaded. All beings are in Me, but I am not in them.",Verse 9.5: "And yet everything that is created does not rest in Me. Behold My mystic opulence! Although I am the maintainer of all living entities and although I am everywhere, I am not a part of this cosmic manifestation, for My Self is the very source of creation."

In next approach I explain that the inside and the outside of said spherical membrane also has a Yin and Yang aspect. The inside is yang, and the outside is yin. Since the membrane is dynamic various enfoldings are possible.

The basic image of the membrane on the left comes from a website on beautiful mathematical 'eversions', but the membrane is there completely intersectable (and makes it possible to turn a sphere inside out) which is not possible in our approach. Our point of view is that the membrane is non-breakable, indestructible. It can penetrate but never can break, neither be cut or thorn in pieces. This image offers the possibility to visualize in another way the Prior-geometry (Wu Chi), but also to explain the famous Yin Yang duality that comes from WU CHI.

In the empty sphere there is however NO Yin and Yang! The spacetime membrane has two sides and we can call the inner side: the YANG side since that represents a CLOSED system, and the outer side: the YIN side. This is however a conceptual difference. The manifestations as holons on both sides are always due to a unique combination of both aspects. The oscillating dynamics of Prior-Geometry will bring on both sides holons and blankets (layers) of holons of growing complexity. Some people will call that complexity of 'unitities' holographic (cf. Bohm) but it is in fact holonistic.
The combinations of Yin and Yang are symbolically expressed in the I Ching (Book of Changes) by 64 combinations of Yang (full line) and Yin (broken line) and offer basic frames (by Hexagrams) which are also used for divination.
With pelastratic layers we prove that the I Ching combinations represent various combinations of spacetime membrane layering, each with unique properties caused by other type of internal friction. We show also that there are more basic combinations than I Ching provides (cf. numbers).

You will recognize the basic Yin Yang logo in the image on the right. The totality is a restructured shape of the membrane sphere. Inside the sphere is now a zone of the outside. So the outside is inside the inside. ;-). Yet we can look for some basic combinations of these two positions, and that brings us 4 BIGRAMS or 4 different holons, each with another layering history.

You can notice that the YANG holons appear on the YIN side of the sphere ! We see here how the manifestations have DUAL aspects. For example: a YANG person (shorter length like women) have a more YIN spirit (e.g. will talk more).

I used a double layer for the 'old' Yin and Yang, and you see that the two coupling peaks are empty (not pushed by another peak). For the 'young' Yin and Yang I used a simple deformation of the membrane provoked by a contacting membrane peak (oscillation). Both old and young contain locally two layers but the old ones are separated by two membrane parts. (the green dotted line is the inner boundary of the outer passive tube.)

Another point is that there are more ways to present for example Old Yang, such as an outwards self-pelastrating tube (see holon Nr. 10 on the consciousness page3) or a straight pelastratic coupling but at the INSIDE of the total system.

This images shows us that the Old Yang can appear at the outside of the sphere ... but also at the inside. In both cases the Yang holons are covered with Yin layers. The difference in position has although an important consequence: The outside old yang holon and tube can expand without limits, but the inside old yang holon can only grow within the limits of the inside yin zone. If this inside old yang has sufficient power he can deformate however also the Yin zone and provoke an pelastrating action like a Young Yang.

Such new combinations bring us more complicated (multilayered) holons like we see in TRIGRAMS and Hexagrams. I Ching refers to 64 theoretical combinations but our approach gives much faster much more geometrical combinations of the spacetime membrane, and we see this as the 'real' development of our Universe.

Here we symbolize with different colors how the Young Yang holon layers will have friction between them. This local friction will cause excitations and oscillations which appear in our world like ElectroMagnetism, Radiation, etc.
